Manual. Everything is done using the setkey utility; I don't use GIF or
anything else. The tunnels just *stopped* the instant I put in the new
kernel.

As far as I can tell there's nothing wrong with sending data (e.g. a 'new'
kernel system can ping an 'old' kernel system via an IPSEC tunnel and the
old system will receive and reply to the ping with its own ESP packet going
back to the originator, but it is then 'lost' in the sending system's kernel).

A 'new' system talking to another 'new' system is just one way - the ESP gets
to the destination but never emerges from it.

If anyone else can confirm this problem and/or suggest a work-around I'd
appreciate it.
